Let me know how we can proceed with that. what should be the next step.

Theory of Operation:
The Silicom Bypass Network Interface Cards (NICs) are network cards with paired ports (2 or 4).
The pairs either act as a "wire" allowing the network packets to pass or insert the device in between the two ports.  When paired with the on-board hardware watchdog or other failsafe, they provide high availability for the network in the face of software outages or maintenance.

The software requirements are for a kernel level driver that interfaces with the bypass and watchdog, as well as for control software. User control can be either the provided standalone executable
(/bin/bpctl) or the API exposed by the Silicom library. 

The current driver uses a device specific /proc interface.
That API programming model will not likely be acceptable in a standard network driver.
Please consider doing something generic with netlink.
